There are two darners that look very much alike, the Black-tipped (Aeshna tuberculifera) and the Shadow Darner (Aeshna umbrosa). The differences are somewhat subtle, so I spent a great deal of time identifying the egg-layers that I photographed for today’s post, vacillating back and forth between the two species. I finally zoomed in on one photo and determined that the lateral stripes on its thorax were outlined in black, making it a Black-tipped Darner (Shadow Darners lack this outline, and lack coloring on the last abdominal segment). That said, while I knew the identity, I neglected to make sure my post reflected this, and once again, a reader was kind enough to point this out. Thank you, Mike Blust!
